MOSCOW, December 5 (RAPSI) – Police arrested a former defendant in a Moscow summer riots case Sergey Abanichev in the Tverskoy District Court’s building on Thursday, RAPSI reports from the ground.

Reasons for the arrest were not disclosed.

Earlier, five defendants in the 27 July mass riots case including Abanichev were withdrawn from criminal prosecution due to the lack of criminal elements they had been charged with. The decision was made based on the results of an objective legal evaluation of all examined materials including video records, according to the Investigative Committee.

Unauthorized rallies in support of candidates seeking to become lawmakers of the Moscow State Duma but refused registration by the Election Commission were held on July 27 and August 3 in central Moscow. Over 1,000 people were arrested for various violations as a result.

Following the 27 July rally, the Investigative Committee criminal cases were opened. Investigators believe that the protest action was held with the use of force against representatives of authority.

Several activists have been already convicted and sentenced. Prosecution of five defendants has been dropped.
